How To Install LEMP on Ubuntu 16.04

LEMP is a variation of the ubiquitous LAMP stack used for developing and deploying web applications. Traditionally, LAMP consists of Linux, Apache, MySQL, and PHP. Due to its modular nature, the components can easily be swapped out. With LEMP, Apache is replaced with the lightweight yet powerful Nginx.

  • Install LEMP on Ubuntu 16.04

First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

Note: If another web server like Apache2 was installed in your system, remove it first to avoid conflicts. To uninstall Apache, run the following commands:

  • Installing Nginx on Ubuntu 16.04

Install Nginx with apt-get, which is the default package manager for Ubuntu:

Start Nginx service using the following command:

You can verify that Nginx is really running by opening your favorite web browser and entering the URL http://your-server’s-address, if it is installed, then you will see this:

  • Configure Nginx web server

To get Nginx to work with PHP correctly, we need to make changes to the Nginx configuration file. This guide we will be using a simple Nginx config file:

  • Installing and Configuring PHP on Ubuntu 16.04

Install PHP on the Ubuntu 16.04 with the following command to begin the install:

Once the installation is finished, edit the server php.ini file and change the cgi.fix_pathinfo parameter value to 0. By default it will be commented out with a semi-colon and the value set to 1 which practically ensures that PHP will attempt to execute the closest file available when a requested PHP file can’t be found. This is a bad security practice, so let’s change it. Execute the below command:

Now find the cgi.fix_pathinfo line, uncomment it and set the value to 0. Save and close the file.

Your server should restart Nginx automatically after the installation of both MySQL and PHP. If it doesn’t, execute this command:

To test PHP, create a test file named info.php with he content below. Save the file, then browse to it to see if PHP is working:

Copy the following into your text editor:

Try to access it at http://your_server_ip/info.php . If the PHP info page is rendered in your browser then everything looks good and you are ready to proceed further.
